CONTROLLING MECHANISM FOR FERTILIZEFP-SPREADERS.

Specification of Letters Patent.

Patented Oct. 9, 1906;

To all whom it may concern.-

Be it known that I, CL MENT L. V. KIN- NEY, a citizen of the United States, residing at Newark, in'the county of Licking and State of Ohio, have invented certain new and useful Improvements in Controlling Mechanism for Fertilizer-Spreaders, of which the following is a specification.

y invention relates to a new and useful improvement in controlling mechanism for fertilizer-Spreaders.

The object of the invention is to provide means associated with the beater-controlling mechanism for preventing the starting of the feed mechanism when the beater is thrown out of gear or not running, also to throw the feed mechanism out when the beater is thrown out if both should be operating, thus preventing the load from being forced against the beater and injuring the same.

Finally the object of the invention is to provide a device of the character described that will be strong, durable, and eflicient and one which will be simple and comparatively inexpensive to make.

With the above and other objects in view the invention consists of the novel details of construction and operation, a preferable embodiment of which is described in thespecification and illustrated in the accompanying drawings, wherein- Figure 1 is a partial side elevation of broken portions of a spreader-body. Fig. 2 is a side elevation of a spreader-body and showing one of the wheels broken away to illustrate the beater-driving means. Fig. 3 is a plan view, some of the parts being broken away to illustrate mechanism 1 'ng beneath. .Fig. 4 is a transverse vertica sectional view taken on the line as w of Fig. 1 and looking toward the head of the body. Fig. 5 is a partial transverse vertical sectional view taken on the line y y of Fig. 2 and looking toward the head of the body. Fig. 6 is an elevation of one of the rod-supporting brackets, showing a portion of one of the side-boards of the body in vertical section. Fig. 7 is a detail plan view of the slide-bar and the clutch-lever and their component parts, and Fig. 8 is an elevation of the parts shown in Fig. 7.

Before entering into a detailed description of my invention it is thought expedient to call attention to my application for patent upon feed-regulating mechanism for fertilizer-spreaders, patented February 7, 1905, No. 781,956. The present invention is designed more especially to be used in connection with the spreader shown in the said application and is adapted to cooperate with certain parts of the said spreader, which will be hereinafter referred to.

In the drawings the numeral 1 designates the spreader-body, which may be of any approved construction and provided with the usual side-boards 2. At the rear end of the spreader I arrange a suitable beater 3, fixed upon and adapted to turn with a transverse shaft 1, which is suitably supported in the side-board 2. One end of the shaft 4 is extended some distance beyond theouter side of one of the side boards 2 and carries upon its outer end a loosely-mounted pinion 5, which is held against displacement by a suit- .able cotter-pin or the like 6. The pinion 5 upon its inner face and concentric to the shaft 4 is formed with an internal rack 7, which with the pinion 5 constitutes the driving member of a clutch. Arranged between the side-board 2 and the pinion is a slidable clutch member or sleeve 8, which is caused to turn with the shaft by reason of a key or spline 9, as shown in Fig. 5. A spring 10 is interposed between the clutch member 8 and the sideboard 2 or a plate 11, secured upon the side-board, so as to tend to force the sliding clutch member 8 into engagement with the rack 7, it being understood that the clutch member is also formed with teeth adapted to mesh with the rack 7. The pinion 5 meshes with a gear 12, loosely mounted upon a stubshaft 13, projecting from the side-board 2, and which shaft loosely supports upon its outer end a sprocket 14, which is suitably connected with the gear 12, so as to impart motion to the said gear when the spreaderbody is moved forward. The sprocket-Wheel 14 is connected, by means of a chain 15, to a large driving-sprocket 16, keyed upon the usual rear axle 17 of the spreader.

It is apparent that motion will be transmitted from the large sprocket 16 to the sprocket 14, which in turn transmits the mo tion to the gear-wheel 12, and the latter, meshing with the pinion 5, will convey the motion thereto. It is apparent that when the clutch member 8 is thrown out of engagement with the pinion 5, as shown in Fig. 5, the beater will remain idle, although the pinion will be revolved as the spreader is propelled forward. However, upon throwing the clutch member 8 into engagement with the rack 7 of the pinion 5 motion will be imparted to the beater and the same revolved to spread the fertilizing material.

For the purpose of throwing the clutch member 8 into and out of engagement with the rack 7 I form the said clutch member 8 with a groove 18 extending entirely around the same and concentric to the shaft 4. Upon the plate 11, which is suitably secured to the outer face of the side-board 2, Ipivotally support between ears .19, extending outwardly from the plate, a forked lever 20. The lever 20 straddles the member 8 and has its forked ends engaging in the groove 18, so as to allow the said member to revolve, but arranged to move the member back and forth upon the shaft 4 in the usual manner. The lever at its upper end is provided with an angularfaced lug 21, adapted to engage with an angular-faced .lug 22, projecting laterally from a slide-bar 23. The spring 10, tending to force the clutch member 8 outward and into engagement with the rack 7 of the pinion 5, it will be apparent that when the slide-bar 23 is moved forward the lug 22, riding along the face of the lug 21, the upper end of the lever 20 will be forced outward and its inner end carried inward. This draws the clutch member 8 out of engagement with the rack and at the same time compresses the spring 10, so that when the slide-bar 23 is movedrearwardly the lug 22, riding rearwardly off the face of the lug 21, allows the upper end of the lever 20 to be forced inward and its lower end and the clutch member 8 outward, thereby causing said member to engage with the rack 7 and transmit motion to the shaft 4. The slide-bar 23 is provided with a slot 24, through which project a pair of headed studs 25, which support and guide the slide-bar and prevent displacement of the same. A rod 26, supported in brackets 27 upon the side-board 2, is engaged at its rear end with the slide-bar 23 and pivotally connected at its forward end to a hand-lever 28. The hand-lever is pivotally supported upon a plate 29 and extends upwardly through a guard 30, which limits its forward and rearward swinging movement.

For preventing the starting of the feed mechanism when the beater is out of gear or the hand-lever 28 in its forward position, as shown in Fig. 2, I pivotally connect to the hand-lever 28 a link 31, which is ivotally connected at its forward end to a sliort arm 32, fixed upon the end of the transverse shaft 33*. The shaft, 33 passes through the sideboard 2 to and through the opposite sideboard 2 near the head of the body, as clearly shown in Figs. 3 and4. On its opposite end the shaft 33 fixedly supports a second short arm 34, similar to the first-named arm 32.

1 However, the second. short arm 34 is disposed at right angles to the arm 32, as clearly shown. The arm 34 is provided with a laterally-extending lug, which is adapted to en gage and stand in front of an elongated stoppiece' 36 when the heater is thrown out of gear and the hand-lever 28 in its forward position, as shown in Figs. 1 and 2.- The stoppiece 36 is secured, by means of a clamp 37, to the setting-rod 50, supported upon the side-board 2 in brackets 39. The rod 50 is pivotally connected at its rear end to the lever 33 of the feed mechanism and at its forward end has a pivotal connection with the hand-lever 51, which is pivotally supported upon the bracket 52. The numerals 50, 33, 51, and 52 will be found to correspond with the same numerals and parts in my former application, herein referred to. In order to start or set the feed mechanism, it is necessary to move the lever 33 forward by means of the handle, which is also swung forward. In Fig. 1 both the hand-lever 51 and the lever 33 are shown in their rearward positions, indicating that the feed mechanism is out of operation, and the lug of the short arm 34, standing in the path of the stop piece 36, it is evident that the hand lever 51 cannot be swung forward, and thus the operator is prevented from throwing the feed mechanism into operation when the beater is not running and the clutch member 8 out of engagement with the rack 7 of the pinion 5. (Shown in Fig. 5.)

It willalso be observed that if the beater is thrown in gear and the second short arm 34 swung downward and its lug 35 out of the path of the stop-piece 36, and the feed-setting mechanism being thrown in upon the lever 28 being moved forward to throw out the beater, the arm 34 will be swung upward, its lug 35 engaging the stop-piece 36, owing to the latter s length, and moving said stop-piece 36 and its rod rearward, thus throwing the feed-setting mechanism out. From this it will be apparent that the feed mechanism will always be inoperative when the beater is out of gear. However, when the hand-lever 28 is swung rearwardly, sliding the bar 23 rearwardly and the lug 22 off the lug 21 allowing the compressed spring 10 to throw the clutch member 8 into engagement with the beater in operation, the link 31 is at the same time pulled rearwardly by the hand-lever 28, causing the short arm 32 to move downward and rearward to a horizontal position, and thus giving the shaft 33 a quarter-turn. The shaft being given a quarter-turn or moved one-fourth of a revolution, the second arm 34 being disposed at right angles to the first arm 32 is also moved downward and forward a quarter of a revolution, which throws its lug 35 out of the path of the stop-piece 36, so that the said stop-piece is free to move forrack 7 of the pinion 5, thereby setting the ward at any time. The hand-lever 51 may be now swung outward and by means of its rod 50 move the lever 33 forward, setting the feed mechanism in operation.

It is thought that the operation and construction will be clear from the foregoing, and it is apparent that a simple and efficacious device for controlling the parts is provided.

Having now fully described my invention, What I claim, and desire to secure by Letters Patent, is

1. The combination with a beater-controlling mechanism and feed-setting means, of a stop carried by the feed-setting means, and a locking device operated by the beater-controlling mechanism and adapted to be moved into and out of the path of the said stop.

2. The combination with a beater-controlling mechanism and a feed-setting means,

of a locking device comprising a transverse shaft, a locking part carried upon the shaft and adapted to be moved into the path of the feed-setting means, and means for connecting the shaft with the beater-controlling mechanism to cause the said shaft to be moved by the said beater-controlling mechanism.

3. The combination with a beater-controlling meohanism and a feed-setting mechanism carrying a stop-piece, of a locking device comprising a transverse shaft connected at one end to the beater-controlling mechanism, and a projection carried on the opposite end of the said shaft and adapted to be moved into and out of the path of the said stop-piece to lock or release the feed-setting mechanism.

In testimony whereof I aflix my signature in presence of two witnesses.
